Description of drawings
Fig. 1 is the scantling plan of this cleaning device.
Fig. 2 is the cleaning principle schematic of this cleaning device.
Fig. 3 be this cleaning device apply the voltage schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is specifically described.
Device of the present invention mainly is comprised of high voltage source, metal electrode board 11, insulation collecting board 13 etc., and metal electrode board 11 and pollution 2 of metal surfaces are wired on high voltage source the two poles of the earth, form electric field between two-plate.
Be connected on high voltage source the two poles of the earth with a plurality of most advanced and sophisticated 12, two metallic plates on metal electrode board 11, wherein on a metallic plate, the tip arranged, can be considered the battery lead plate 11 of cleaning device; Liquid lamella 22 is arranged on another metallic plate, can be considered and pollute metal surface 2.
After having applied high pressure between two metallic plates, formed highfield will make the liquid pollutant thin layer produce induction, and the thin layer outer surface will be assembled free electron, and thin layer is also with polarized simultaneously.Final under the effect of electric field force, form taper outwardly, form taylor cone (Taylor-Cone), then produce jet (jet), the tip of directive positive electrode.The contaminant collecting plate 13 that is positioned between two battery lead plates will be collected liquid pollutant.
